| titleOfInvention | The preparation method of Cu/Mg/Al/Zr high dispersing copper based dehydrogenation catalysts |
| abstract | The present invention relates to the preparation method of Cu/Mg/Al/Zr high dispersing copper based dehydrogenation catalysts.Mantoquita, magnesium salts, aluminium salt and zirconates are dissolved in deionized water by the present invention in proportion, and wiring solution-forming A, precipitating reagent sodium carbonate and sodium hydroxide are dissolved in deionized water, wiring solution-forming B, and mixing quality ratio is 1: 0.5~2；Burin-in process in deionized water is added dropwise in solution A and solution B under stirring condition；Mixed liquor is filtered, washed, dry after obtain copper magnesium-aluminum-zirconium catalyst precarsor, hydrotalcite is pulverized, add water formation distiller liquor, carry out forming processes, obtain article shaped；By calcination process after drying, O composite metallic oxide catalyst is obtained；It is fitted into reactor, reduction activation is handled in atmosphere of hydrogen, obtains the copper magnalium catalyst for preparing o-phenyl phenol.Instant invention overcomes catalyst life is too short and mechanism and the unclear defect of deactivation cause.Present invention reduces the cost of production o-phenyl phenol, catalytic activity is high and improves the stability of catalyst. |
